Pseudographical recognizer#6862
Let us define a pseudographical image to be a rectangular matrix of the characters '.', '-', '|', '\', and '/'.
The character '.' denotes empty space on the image. A horizontal line segment is given as a set of '-' characters in adjacent cells in the same row of the matrix. A vertical line segment is given as a set of '|' characters in adjacent cells in the same column of the matrix. Similarly, a diagonal line segment is given as a set of '/' or '\' characters in adjacent cells in the same diagonal of the matrix. Of course, a line segment going from Northwest to Southeast has to be given using the '\' characters and a line segment going from Southwest to Northeast using the '/' characters.
Write a program that, given a pseudographical image, determines if it contains exactly one line segment – horizontal, vertical, or diagonal.
Input file contains several test cases. The first line contains the number of test cases (1 \le T \le 100). Next follow the descriptions of each test case. The first line of the test case description contains two integers and (1 \le N, M \le 10), the number of rows and columns of the matrix, respectively. Each of the following lines of the description contains exactly symbols '.', '-', '|', '\', or '/'.
Output file consists of lines, one line per each test case. This line should contain the word CORRECT if the input image contains exactly one line segment, or the word INCORRECT otherwise.
